A valve includes a body including an inner bore extending between a first port and a second port, a seat, and one or more restrainers and a disk that is moveable between the seat and the one or more restrainers such that a first pressure that is less than 1 pascal and applied in a first direction causes the disk to move from a first position towards a second position to permit fluid communication between the first port and the second port. A metamaterial scaffold including a structure defining a lumen, at least a portion of an outer or non-lumen surface of the structure is coated with a plurality of biological cells, and wherein the structure is composed of a metamaterial.

Metamaterial scaffolds and uses thereof

A method for fabricating an electrode includes forming a 3D shell having a hollow interior and defining one or more openings, and directing an electrically conductive liquid through at least one of the one or more openings of the 3D shell, such that the 3D shell is at least partially filed with the electrically conductive liquid. The electrically conductive liquid can be caused to solidify within the 3D shell to form a solid electrode, or can remain a liquid to form a liquid electrode. The 3D shell can be formed having the one or more openings using a 3D printing process such as a two-photon writing system. The surface tension of the electrically conductive liquid aids in retaining the electrically conductive liquid within the 3D shell. The electrode can contact a tissue sample through one of the openings in the 3D shell.
